OLATHE, Colo. -- A western Colorado police officer faces a domestic violence charge after a woman claimed he beat her regularly as part of a relationship contract that called for corporal punishment.

Olathe Officer Michael Percival was arrested June 26 on suspicion of misdemeanor assault. Town Attorney David Masters said Percival has been suspended pending a hearing.

There was no answer Thursday at a number listed for Percival.

A deputy booking the woman into jail on unrelated charges discovered marks that the woman said came from beatings from a belt.

Investigators said the woman showed them two contracts allegedly written by Percival that concerned her hygiene, sexual behavior and clothing and spelled out punishments, including spankings with a belt. The contract detailed "what (Percival) expected from her on a daily and weekly basis," according to an affidavit obtained by the Montrose Press.

The woman said she was to be punished with 50 lashings for asking why she wasn't included in a fishing trip, but she said Percival agreed to split the punishment into two 25 lashings each session.

"(Woman) said she had to count each lashing and tell him 'thank you' after each strike and if she failed to count or miscounted, Percival would start over from the beginning," MCSO Investigator David Harrison said in the affidavit.

Percival was arrested by officers from his own police department. He was held for investigation of third-degree assault and domestic violence.

A previous domestic violence case against Percival was dismissed in 2007, according to Montrose Press.
